Knowing that Chris Sr. was the one who was shot the most times brings a lot of other facts into focus for me. He and Gary were, I believe, shot first and I don't think it was pre-planned given the messy crime scene in two rooms, the dragging of the bodies, the number of shots, etc. I think more than one person went there to conduct drug-related business (buying, selling, warning off competition, or the like). Things got heated, shots were fired, Chris and Gary were murdered. The murderers said "oh, $#%$" and tried to clean up the scene by dragging the bodies into a back room. Then they realized that other people knew of their existence/relationship to Chris/Gary, and calmed down and made a plan to get rid of all of them. Kenneth was the last one they murdered and by then, I think they had a half-baked idea to make it look like a "cartel" or gang killing so they left the money. I know the AG said they went to great lengths to cover their tracks; what he didn't say was that they were actually any good at covering their tracks. I think LE knows who it is, has had them under surveillance, and arrests/indictments are forthcoming. And I don't think familial suspects and drug suspects are necessarily mutually exclusive in this case.
